Filtration aided by nanomaterials
May 4, 2011—Chinese researchers have shown for the first time that nanomaterials made from titanium dioxide can be used in cigarette filters to reduce significantly the amount of harmful chemicals inhaled by smokers, according to a Royal Society of Chemistry story.
